You can't, as such. There are at least two workarounds I can think of.

print -l a(/e:'REPLY=3D$REPLY/b(/)':)
(this one quickly gets messy to nest)

() { print -l $^@/b(/) } a(/)
() { () { print -l $^@/c(/) } $^@/b(/) } a(/)
You may need to add N in the glob quals here too, or intermediate
directories with no children would produce a glob error.

Note more specifically also that **/*(.) does not recurse through
symlinks to directories, ***/*(.) would.
